"So the titanic showdown between Facebook and Google might not be the News Feed vs. Google+ after all. It might be Facebook Camera vs. Project Glass. It might, in fact, be pictures vs. vision." Sounds esoteric, but bear with author Robin Sloan, because I think he's clearly on to something. By extension, this.

I expect first-person videos to become a new "standard" way to film sport, events, life. I think the tiny difference of POV - moving from a handheld camera to a head-attached one - is far more important and far-reaching in our psyche than many think it will be, and may be as important as the ubiquity of cameras nowadays. It is no accident that many scifi writers envisioned that one day, we could see what other people see - literaly, from their point of view, through artificial camera-eyes or through uploading your memories.
